Title: Film processor

IPC: G03D9/00
Filed: 1987-03-03
Granted: 1991-02-05
Abstract: Abstract of the Disclosure Apparatus for processing a roll of self-developing type film.  The film and a length of flexible sheet material are unwound from their respective spools and laminated to each other with a layer of processing liquid located therebetween prior to being wound as a laminate upon a rotating drum.  After the formation of a visible image within the film, a drive train is energized to drive the spools in a direction which unwinds the laminate from the drum and simultaneously rewinds the film and sheet material upon their spools.  The drive train is continuously connected to the drives for the spools and includes a clutch arrangement which insures that the rotation of the drum in an unwinding direction is under the control of the sheet material drive while the torque delivered to the film drive keeps the film taut without becoming the dominant force in rotating the drum.

Title: Curve generation in a display system
Inventor: CLARK DAVID A
IPC: G09G1/08
Filed: 1988-04-29
Granted: 1992-10-27
Abstract: CURVE GENERATION IN A DISPLAY SYSTEM         ABSTRACT      A curve generator for a display system comprises arc generation means for generating an arc of a circle from data defining the locations of two end points and an intermediate point on the arc.  The arc generation means comprises initialisation means for calculating the angle subtended between a first vector, from a first of the end points to the intermediate point and a second vector from the second of the end points to the intermediate point and arc plotting means for defining a succession of further vectors from said first end point and for calculating, for each further vector, its point of intersection with a counterpart vector, from the second end point, with which it subtends said angle, whereby a succession of further points are plotted on the circular arc.  The plotting logic thus plots the points of the arc with respect to a given point on the arc itself by generating vectors from that given point and enables the computation of the arc to be performed substantially within the system co-ordinate space in which the arc exists, which reduces the number of places of accuracy needed in order to accurately compute the arc.

Title: Quenching process of reaction product gas containing methacrylic acid and treatment method of quenched liquid
Inventor: KURAGANO MORIMASA
IPC: C07C57/04
Filed: 1988-06-23
Granted: 1993-04-20
Abstract: ABSTRACT        In order to recover methacrolein and/or methacrylic acid by quenching a reaction product gas obtained by catalytic oxidation of isobutylene or the like, the reaction product gas is charged into a quench column through a double-wall pipe and is then brought into contact with a condensate as a cooling medium.          Deposition of terephthalic acid and the like inside the column is prevented by controlling the temperature of a bottom in the quench column and that of an overhead gas of a quench column unit.  An aromatic carboxylic acid, aromatic aldehyde, metal powder is added to an aqueous solution of methacrylic acid, which contains tere-phthalic acid and the like, so that the terephthalic acid and the like are caused to precipitate for their removal.

Abstract: A  novel  method  for  determining  the  ambient concentrations of a plurality of analytes  in a  liquid sample of volume V litres avoids the undesirable use of high levels of binding agent in immunoassays.  The method comprises loading a plurality of different binding agents, each being capable of reversibly binding an analyte which is or may be present in the liquid sample and is specific for that analyte as compared to the other components of the liquid sample,  onto a support means at a plurality of spaced apart locations such that each location has not more than 0.1 V/K, preferably less than 0.01 V/K, moles of a single  binding  agent,  where  K  litres/mole  is  the equilibrium constant of the binding agent for the analyte; contacting the loaded support means with the liquid sample to  be  analysed,  such  that  each  of  the  spaced  apart locations  is contacted  in the same operation with the liquid sample,  the amount of liquid used in the sample being such that only an insignificant proportion of any analyte present in the liquid sample becomes bound to the binding agent specific for it; and measuring a parameter representative of the fractional occupancy by the analytes of the binding agents at the  spaced apart locations by a competitive or non-competitive assay technique using a site-recognition reagent for each binding agent capable of recognising either the unfilled binding sites or the filled binding sites on the binding agent, said site-recognition reagent being labelled with a marker enabling the amount of said reagent in the particular location to be measured.  A device and kit for use in the method are also provided.

Abstract: A labeling system including a means to compensate for positional shifts of acticles to be labeled is provided.  This system includes a labeling drum for providing a label  to a vessel such as a bottle, a sensor means for sensing a vessel and/or  the  angular  position  thereof  on  a  conveyer,  and a controller for controlling the labeling drum to adjust for a degree of shift between a given labeling area on the vessel and a corresponding labeling head provided on a labeling drum.   A sensor means is provided at a side of the vessel conveyer and provides a signal at every passage of a vessel to a controller. The controller determines the angular position of the labeling drum in response to the signal output from the sensor means by calculating a shift parameter to align a given labeling area of a vessel with the corresponding labeling head of the labeling drum and  provides  pulse  signals  corresponding  to  the  shift parameter to a servo motor connected to the labeling drum.  The servo motor drives the labeling drum so as to advance or retard the rotation thereof to insure alignment between the labeling head and the given labeling area of the vessel.
